3.1a Matter takes up space and has mass. Two objects cannot occupy the same place at
the same time.
3.1b Matter has properties (color, hardness, odor, sound, taste, etc.) that can be
observed through the senses.
3.1c Objects have properties that can be observed, described, and/or measured : length,
width, volume, size, shape, mass or weight, temperature, texture, ,reflectiveness of light.
3.1d Measurements can be made with standard metric units and nonstandard units.
(Note: Exceptions to the metric system usage are found in meteorology.)
3.1e The material(s)an object is made up of determine some specific properties of the
object (sink/float, conductivity, magnetism).Properties can be observed or measured
with tools such as hand lenses, metric rulers, thermometers, balances, magnets, circuit
testers, and graduated cylinders.
3.1f Objects and/or materials can be sorted or classified according to their properties.
3.1g Some properties of an object are dependent on the conditions of the present
surroundings in which the object exists. For example:
temperature -hot or cold
moisture -wet or dry
